Mass Air Flow question

I have a 1997 Nissan HB Pickup truck that has had an issue in the past with stalling. I got the MAF sensor rebuilt and it lasted for 18 months and now it finally bit the dust and threw the dreaded p0100 code.

I have found through other posts that you have to buy the whole Venturi throttle body to get the darn sensor - best price I can find is about $400.

I have done LOTS more digging online and found just the MAF sensor online for $149 - $250 - new.

My husband thinks there MIGHT be a reason that you have to buy the whole throttle body since they are technically sold together through Nissan. Of course, I would rather just spend $150 instead of the $400 but if there is a good reason to buy the whole thing, I will. I just want this truck to run!

Any expert opinions out there?

have him try a j/y, he can get the whole thing for less than 150. most j/ys have some sort of warranty so if it doesnt work they will take it back.

Dave,

I wish I could find a j/y throttle body. No one seems to have them for a 4cyl automatic. Lots of people have the 6cyl...... Very frustrating.

I called the Nissan service/parts and talked to the service guy. He tells me that there is no good reason (that he can think of ) for buying the MAF with the throttle body - they only sell it that way because that is the way it comes from Nissan. There is no calibration that he is aware of.

I was hoping the last one would have lasted more than 15 months......

I found some aftermarket (non branded) MAF's for $149 with a one year warranty that are supposed to be brand new. Maybe this would be better than a rebuild again?

My truck is a 1997 4cyl auto trans with MAF Hitachi AFH55M-12.

If a different throttle body will swap out - along with a different MAF sensor????

I dont know if there are interchangeable parts that will play nice with the 1997 PCM.

Anyone know about this?

better to just get the MAF sensor new...less than half the price than the throttle body, and no reason to replace the whole thing. wish you had said where you found it originally for $150. took forever to find. here's the link I turned up

Yep - that is what I found too! Here is a link that works as of Oct 2009: D21 Pickup | 1997 | Nissan | All Ignition

Its also on ebay right now: NISSAN D21 Pickup 2.4L MASS AIR FLOW METER AFH55M-12:eBay Motors (item 390101929092 end time Oct-10-09 21:39:31 PDT)

Also found at a place called costparts.com for $96.00: Mass Air Flow Meters/Sensors

My rebuilt MAF went out again - going with new this time. Not sure where to purchase from - think I will check out costparts.com first. I will report back - hopefully with good news.

At least these links give us all other options than going through the dealers and buying the throttle bodies too! Keep your fingers crossed for me!

Just an update on the MAF

The part on costparts.com did not work for my truck even though they state it is a replacement for the AFH55m-12. The thing that I think was the issue is that the sensor wires are located one up and one down. THe original Hitachi OEM part - the sensor wires are located at the same height. I am waiting to hear about another part before I buy it.

By the way, Auto Mammoth has the exact part you are looking for, The AFH55m-12 for a fraction of the cost of the OEM version. It has a 5 year warranty. Check them out, they are friendly people to work with and actually have ASE certified mechanics on staff. And it's only $79.99. I got one for my 1997 Nissan pickup and it works like a charm.
